Nitrogen monoxide is a pollutant in the lower atmosphere that
irritates the eyes and lungs and leads to the formation of acid
rain. Nitrogen monoxide forms naturally in the atmosphere according
to the endothermic reaction:
N2(g) + O2(g) ----> 2 NO(g) Kp
= 4.1 * 10-31 at 298 K
Use the ideal gas law to calculate the concentrations of nitrogen and oxygen present in air at a pressure of 1.0 atm and a temperature at 298 K. Assume that nitrogen composes 78% of air by volume and that oxygen composes 21% of air. Find the "natural" equilibrium concentration of NO in air in units of molecules/cm^3. How would you expect this concentration to change in automobile engine in which combustion is occurring?

Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide is N2(g) + O2(g) +2NO(9) The heat produced by an automobile engine is sufficient to convert some of the nitrogen and oxygen in the air to nitric oxide. The spontaneity of a reaction can be determined from the sign of, A-G • A reaction...

Nitrogen oxide, NO, is a common pollutant produced by the reaction of nitrogen and oxygen gas. Since these gases are several major components of air, nitrogen oxide forms when air is heated in furnaces, engines and other high temperature combustion reactions. Given the standard enthalpy of formation for NO (g) = 90.25 kJ / mole and using the absolute entropies shown in the table below, the free energy change for the reaction at 25.00 ºC can be calculated, and equals...
